WPŁYW STOSOWANIA WAPNA, POPIOŁU Z BIOMASY I KOMPOSTU ORAZ PREPARATU EM NA PLONOWANIE I KOMPONENTY PLONU PSZENICY

Field experiment was conducted in 2013 in Duninowo (54 o 539’ N, 16 o 830’ E). The experimental factors were: I. factor - 6 variants of fertilization, and II. - two level of EM preparations. The aim of this study was to evaluate the impact of ash from biomass by comparing its effect with the calcium fertilizer and compost BIOTOPE in conjunction with the preparation of microbiological Effective Microorganisms (EM). The impact of ash from biomass introduced into the soil on yield and yield structure and physiological parameters of spring wheat was analyzed No significant impact of the various variants of fertilizer application on the yielding
